Specification of Letters Patent.

Patented April 28, 1908.

Application filed March 6, 1906. Serial No. 304,606.

To all whom it may concern:

Be it known that we, HERMAN J. EHRLIOH and HERMAN B. EHRLICH, citizensof the United States, residents of Brazil, in the county of Clay andState of Indiana, have made a certain new and useful Invention inValves; and we declare the following to be a full, clear, and exactdescription of the same, such as will enable others skilled in the artto which it appertains to make and use the in vention, reference beinghad to the accompanying drawings, and to letters or figures of referencemarked thereon, which form a part of this specification.

Figure 1 is a perspective view of our valve.

Fig. '2 is a section on the line 22, Fig. 3.

Fig. 3 is a section on the line 33, Fi 2.

The invention has relation to valves, having for its object theprovision of an im proved device of this character, which will beefficient, economical, and durable.

With this object in view, the invention consists in the novelconstruction and combinations of parts, as hereinafter set forth.

In the accompanying drawings, illustrating the invention, the letter adesignates the valve seat, having four standards or extensions I)connected at their outer ends by cross pieces 0 having perforated endsfitting over such standards, forming a valve cage. Securing nuts areprovided for the cross pieces,

. such nuts engaging the threaded outer end portions of the standards.The valve seat has cross bars (1 flush with its outer surface to keepthe valve from cupping. These cross bars are of slender character.

0 is the valve, which is solid or imperforate, fitting closely withinthe extensions of the seat, and normally resting upon the seat and itscross bars. This valve is usually formed of rubber as shown, and has ametal head f connected to the body of the valve in any suitable manner,said head having a central boss or extension g.

The cruciform connections of the extensions b are provided with centralthreaded alined perforations h, for the engagement of a set screw 2',having a slotted inner end for connection of the smaller end of aconical coil spring j, extending from the set screw 6 to the valvearound the central boss of the head thereof, which boss is largecompared with the diameter of the set screw.

Our invention dispenses with a stem to the valve, and provides a solidvalve, increasing the durability of the parts and preventing leakage.\Ve also dispense with a web in the seat which is liable to chokethrough accumulations. By means of the set screw having connection withthe valve spring the tension of the spring may be readily adjusted tosuit the requirements or take up wear. The

valve is confined in the cage for a true movement.

Having thus described our invention, what we claim and desire to secureby Letters Patent is A valve having a seat provided with separatedstandards having threaded outer end portions, removable cross pieceshaving perforated ends fitting over said standards, securing nutsengaging the threaded end portions of said standards, said cross pieceshav ing central threaded alined perforations, a set screw engaging thecentral perforations of the cross pieces, and having a slotted inner endportion, a valve having a metal head provided with a central boss, and aconioally coiled spring having its contracted end portion engaging theslot of said set screw and having its expanded end portion surroundingthe central boss of the metal head and in contact with the valve.

In testimony whereof we aflix our signatures, in presence of twowitnesses.
